If you dont know how to find the area of a circle, then you need to review your course material.

um i did and the reason i came on here is for you people to atleast ehlp me understand it . ? @amistre64

Do you remember the formula? You answered, No Not: I did, not, here it is, nothing. just No. So, how do we calculate the area of a circle? post your thoughts, and then we can proceed.

goodness i hate math.
amistre64
  • amistre64
this isnt math, its just a formula. formulas are memory stuff, not math perse. and there is something off in your option, that i agree.

area equals pie r2
amistre64
  • amistre64
oh good, my brain was set on circumference ... i would have gotten it wrong by a simple mistake.
amistre64
  • amistre64
pi r^2 what is our radius?
anonymous
  • anonymous
2
amistre64
  • amistre64
half of 4 yes. so pi 22 assuming your paste ate the exponent marker. and now, this is why you finding the formula was important, I was considering using 2 pi r instead - which was wrong in my head.

so the answer is 3.14 * 2 square

Jamie has a deck of 60 sports cards, of which some are baseball cards and some are football cards. Jamie pulls out a card randomly from the deck, records its type, and replaces it in the deck. Jamie has already recorded six baseball cards and nine football cards. Based on these data, what is, most likely, the number of baseball cards in the deck? 12 15 24 30

what is our current ratio?
anonymous
  • anonymous
what do you mean ?
anonymous
  • anonymous
oh 15
amistre64
  • amistre64
a ratio is the number of items in one set, compared to the number of items in a different set. say I have 3 apples and 2 oranges, the current ratio of apple to oranges is: 3:2

i feel so stupid even though i have a a in math lol
amistre64
  • amistre64
15 is required 6 of one, 9 of the other, and 15 total 6 :9 :15 now the ratio stays consistent for any multiple, say k 6k :9k :15k we want the value of 6k we know that 15k = 60, since we have a total of 60 cards in the entire deck what should the value of k be?

  • anonymous
4
amistre64
  • amistre64
correct, so 6*4 is our solution
